These results are consistent with CAT #2254 published in 2012, which found that Invisalign does not correct malocclusion as well as braces. Clear aligner treatment is recommended only for the correction of simple malocclusions.

Clear aligners are generally successful in leveling and aligning dental arches. They are effective in controlling anterior intrusion, posterior bucco-lingual inclination, and upper molar bodily movements of about 1.5 mm. However, clear aligners are not effective in controlling anterior extrusion, anterior bucco-lingual inclination, and are also not effective in controlling the rotation of rounded teeth.

The Evidence

Because of the number, quality, and heterogeneity of the studies, the results of this systematic review should be interpreted with discretion.

Applicability

These findings may be useful in an orthodontic clinic or a general dental practice, if a patient inquires as to whether clear aligners or traditional braces would be the most efficient method of treatment for their particular case.
